User-controlled navigation takes place on or in the vicinity of the display screen, whether by hard or soft key actuation.

RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/US2007/073178, filed Jul. 10, 2007, which claims benefit of U.S. Provisional Application No. 60/830,072, filed Jul. 10, 2006.

TECHNICAL FIELD

The present disclosure relates to mobile communication devices and, in particular, to a modular, configurable, multi-function mobile communication device that can be fully customized to users' personal tastes and desired modes of use.

BACKGROUND INFORMATION

The increasing worldwide popularity of mobile or cellular telephones has transformed the way people live and work, while reshaping the cultural landscape. The proliferation of thousands of models and styles of mobile telephones has turned this one-time marvel of technology into a commodity product. Over 500 million sleek, colorful new mobile telephone sets are sold annually and used to send text and e-mail messages, browse the World Wide Web, play video games, keep track of personal information, take photographs, and store and play music in many different situations, modes, and capacities. The mobile telephone has rapidly become the centerpoint of digital life, as well as a personal fashion statement.

SUMMARY OF THE DISCLOSURE

Preferred embodiments of a mobile communication device combine the latest in communication technology with established patterns of human behavior. Several of the preferred embodiments of the communication device specifically described are those of a mobile telephone. By framing the opportunity within the context of a market that had become greatly commodified and was rapidly fragmenting, applicant identified an opportunity to move away from developing yet another multi-function mobile telephone. The design of the modular multi-function mobile telephone embodies definitions of several user profiles, along with potential use scenarios that range from individuals wanting to stay in touch at all times in a familiar way, to business professionals seeking to easily connect to the Internet and send and receive e-mail messages, and to teenagers wanting to customize in an instant their telephones to a desired look.

Applicants' conceptual exploration of technology, communication, and human behavior revealed certain interesting findings. Although mobile telephones are becoming increasingly smaller, human fingers are not. As a matter of simple practicality, the keypad has remained the largest component of these devices. The keypad is also the most configurable and least expensive component of the mobile telephone. Preferred embodiments separate the keypad from the rest of the mobile telephone components and provide a flexible, functional, and configurable modular communication device called “POD” that can fully and affordably address a user's desire for greater customization.

POD is composed of an information delivery module, called “puck” because of the physical appearance of its preferred embodiments, and an information input module, such as a keypad. The information delivery and information input modules are matable to each other. The puck is a single base unit that can work with a touchscreen keypad or a number of modular keypad or other information input attachments. With the puck, POD addresses different use modes and aesthetic sensibilities of its users. This enables the user to change the look of the product according to personal taste and enhances the functionality of the device to fit the exact occasion and mode of use. The puck preferably contains communication and display signal processing circuitry and associated components of the POD, including a display screen, energy supply (battery), and video camera. Communication signal connectors or other devices are placed on the outside ring or rear surface of the puck. The puck acts on its own as the navigation key and provides on its screen menu (including an on-screen touch sensing keypad) user access to all functionality including telephone, PDA (personal digital assistant), camera, clock, and MP3 music player. Navigation key actuators include mechanical keys or, more preferably, touchscreen function actuation areas. User-controlled navigation takes place on or in the vicinity of the display screen, whether by hard or soft key actuation.

Functionality can be expanded by use of a keypad module that enables the POD to be used as a conventional mobile telephone, PDA, MP3 player, and gaming device. Using common flex-circuit technology, interchangeable keypads can be encased and manufactured inexpensively in many different shapes, finishes, and materials such as leather, fabrics, silicon rubbers, plastics, and metals. In certain embodiments, use in the puck of an on-screen touch sensing keypad enhances POD design flexibility by enabling use of fewer (by elimination of the keypad module) or different functional controls in the information input module. Moreover, accent covers fitted over the back surface of the POD provide another opportunity to readily customize its appearance.

The modular design approach implements a compact, affordable, customizable, and highly functional solution that transcends use and user differences while creating an iconic device.

Additional aspects and advantages will be apparent from the following detailed description of preferred embodiments, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Preferred embodiments of the POD transform the mobile telephone, text message, photographic or video image acquisition, music listening, video watching, or video game experience by offering a modular multi-function communication device that can be easily and affordably customized to meet users' exact needs and desires through a variety of interchangeable attachments. POD is a flexible system based on a shared information delivery module or puck 20, a personable, compact embodiment of which is shown in FIGS. 1A, 1B, 1C, and 1D. Puck 20 preferably embodies a minimal, elegant shape (e.g., round, square, or rectangular) and fits comfortably in hand on its own, can be worn as a fashion statement through jewelry such as a necklace (FIG. 5A) or wrist watch (FIG. 3A), or can be transformed by a number of other information input or keypad modules (FIGS. 2A, 6A, 7A, 8A, 9A, 10A, 11A, 14A, and 15) in many different forms, materials, finishes, and colors.

With reference to FIGS. 1A, 1B, 1C, and 1D, puck 20 is an information delivery module that includes on its front side a display screen 22, on its rear side an image camera 24, and in its interior a power source (not shown), such as a battery, and associated internal electronic circuitry (not shown) that provides signals for delivery of information to a user without user stimulus, with user stimulus, or both. Internal electronic circuitry includes communication signal processing circuitry for receiving, transmitting, or receiving and transmitting one or more of cellular telephone, image camera, and electronic message signals; image display symbology and patterns; or other communication signals presenting visual or audible information to a user. The receipt of cellular telephone, video, and e-mail message signals and the display of image patterns (e.g., time of day) are typically accomplished without coincident user stimulus. Control buttons 30 positioned on a top annular rim 34 at a periphery 36 of puck 20 may be actuated by a user to set a display mode (e.g., clock face or decorative pattern), enable or disable certain functions (e.g., transfer cellular telephone call to voice message), or control certain operating conditions (e.g., control navigation through menu structure). Alternatively and more preferably, the user-controlled actions described above are accomplished by providing a touchscreen (implemented with currently available touch sensing technology) as display screen 22 and touching by the user of function actuation areas of the touchscreen to select the desired functional operation.

FIGS. 1A, 1B, and 1D show puck 20 in the form of a disk having a generally flat front surface 40 and a generally flat rear surface 42. Front surface 40 is of greater area than that of rear surface 42. A beveled side surface 44 interconnecting front and rear surfaces 40 and 42 is sized to mate with a complementary depthwise tapered side surface of any one of many information input module embodiments, several examples of which are described in detail below.

FIGS. 2A, 2B, and 2C show a modular communication device 50 that includes an information input module styled as a conventional mobile telephone form factor keypad 52. Keypad 52 exhibits on its upper surface 54 a conventional set of keypad buttons 56 and receives puck 20 in a circular aperture 58, as shown in FIG. 2B.

FIGS. 3A, 3B, and 3C show a modular communication device 60 that includes an information input module embodied as a keypad styled as a wrist watch band 62. Wrist watch band 62 is made of a flexible, resilient electronic circuit board substrate material, such as Kapton™ polyimide film manufactured by DuPont, which a user can configure to a desired shape and exhibits memory properties that retain the user-configured shape. Watch band 62 exhibits on its outside surface 64 a conventional set of keypad buttons 66 and receives puck 20 in a circular aperture 68, as shown in FIG. 3B. FIGS. 4A, 4B, and 4C show watch band 62 in a folded state representing the shape assumed when a user wears wrist watch modular communication device 60. FIGS. 4D and 4E show watch band 62 in an unfolded, flat state, illustrating, respectively, its inside surface 70 and image camera 24 of puck 20, and its outside surface 64 with keypad buttons 66 and display surface 22 of puck 20.

With reference to FIGS. 2B and 3B, each of circular aperture 58 of keypad 52 and circular aperture 68 of watch band 62 has an inner side surface 74 of complementary beveled shape to that of beveled side surface 44 of puck 20. Electrical contacts 76 positioned on inner side surface 74 provide an interface to deliver signals to and receive signals from corresponding electrical contacts 78 on side surface 44 (FIG. 1B) of puck 20 when it is installed in aperture 58 or 68. Substituting infrared light transmitter and sensor devices for electrical contacts 76 and 78 provides an alternative communication link interface for delivering signals to and receiving signals from puck 20 when it is installed in an information input module. FIGS. 2A and 3A show puck 20 installed in keypad 52 and wrist watch band 62 to form, respectively, conventional mobile telephone form factor modular communication device 50 and wrist watch modular communication device 60. FIGS. 2C and 3C show, respectively, conventional mobile telephone form factor modular communication device 50 held in a user's hand and wrist watch modular communication device 60 worn on a user's wrist.

FIGS. 5A, 5B, 5C, and 5D show an information delivery module adapted to be worn as a necklace pendant 80. Necklace pendant 80 includes puck 20 with a recess 82 formed in its side surface 44 to receive and lock in place an ornamental stem 84. Stem 84 has a free end 86 in which an aperture 88 is formed and sized to receive a necklace 90. FIG. 5A shows a telephone number appearing on display screen 22 of necklace pendant 80 to indicate the identity of the source of an incoming call to puck 20 configured to operate as a cellular telephone. FIG. 5B shows the rear side of puck 20 where the aperture of image camera 24 is located. FIG. 5D shows a clock face appearing on display screen 22 of necklace pendant 80 to represent one possible user selectable steady-state display pattern and source of time of day information. Withdrawing stem 84 from recess 82 enables installation of puck 20 in, for example, keypad 52 or wrist watch band 62 to enable a user to use puck 20 in a different mode in accordance with the keypad module selected.

FIGS. 6A, 6B, 6C, 6D, and 6E show a hand-held modular communication device 100 that includes a small-scale, full-function keyboard 102 having in its top side margin a centrally located arcuate cutout 104, into which puck 20 can be inserted, and a set of keys 106. In this embodiment, electrical contacts 78 on side surface 44 of puck 20 are positioned to align with electrical contacts 76 on open-ended inner side surface 74. Full-function keyboard 102 is especially suited for use with puck 20 configured for use in response to two-hand user operation as a personal digital assistant (PDA) or text messaging module.

FIGS. 7A and 7B show a hand-held modular communication device 110 that includes a game pad module 112 having in its top side margin a centrally located arcuate cutout 114, into which puck 20 can be inserted, and two sets of game control actuators 116 and 118. Game control actuators 116 and 118 represent, respectively, joystick/navigation keys and gaming buttons. Communication device 110 is of similar construction to that of communication device 100 in that electrical contacts 78 on side surface 44 of puck 20 are positioned to align with electrical contacts 76 on open-ended inner side surface 74. Placement of puck 20 in game pad module 112 and programming of puck 20 causes communication device 110 to operate in a gaming mode. Puck 20 can be programmed to perform other functions, such as receive cellular telephone calls, while operating in gaming mode.

FIGS. 8A and 8B show a modular communication device 130 embodied as a vehicle dock input module 132 having in its top side margin a centrally located arcuate cutout 134 into which puck 20 can be inserted. Electrical contacts 78 on side surface 44 of puck 20 are positioned to align with electrical contacts 76 on open-ended inner side surface 74. Vehicle dock input module 132 includes a keypad composed of keys 136 and a separate pickup/hangup button 138, all of which are sufficiently large to accommodate easy activation and numeric entry by a user during vehicle operation. Vehicle dock input module 132 is equipped with a speaker 140 to permit hands-free operation upon initial placement or receipt of a telephone call. An articulating attachment arm 142 secured to the rear surface of vehicle dock input module 132 extends from and is fixed to a vehicle dashboard 144, such as that of an automobile, to allow user positioning of communication device 130.

FIGS. 9A, 9B, and 9C show a hand-held modular communication device 150 configured as a medallion that is sized to fit in the palm of a user's hand and secured by a strap 152 around the user's wrist. An annular information input module 154 includes distributed around its periphery 156 individual numeric keypads 158 that are readily accessible to a user. Annular information input module 114 has a central circular aperture 160 into which puck 20 can be inserted so that electrical contacts 78 on side surface 44 of puck 20 are positioned to align with electrical contacts 76 on open-ended inner side surface 74. Modulator communication device 150 is especially suited for use as a cellular telephone.

FIGS. 10A, 10B, 10C, 10D, 10E, 10F, 10G, and 10H show a modular communication device 170 that folds to the shape of a wallet and includes a keypad and input module 172 having a circular aperture 174 into which puck 20 can be installed. Communication device 170 exhibits a display screen layout similar to that of FIG. 2A with puck 20 installed, but input module 172 is made of the same flexible, resilient electronic circuit board material as that of which wrist watch band 62 is made. Electrical contacts 78 on side surface 44 of puck 20 are positioned to align with electrical contacts 76 on inner side surface 74 of circular aperture 174, as shown in FIG. 10B. FIG. 10D shows display screen 22 of puck 20 and FIG. 10E shows image camera 24 of puck 20 on an inside surface 176 and an outside surface 178, respectively, of modular communication device 170.

FIG. 10C shows a curved direction arrow 180 indicating the folding direction of input module 172 to completely close inside surface 176 on itself and thereby cause modular communication device 170 to appear as shown in FIGS. 10G and 10H. FIG. 10G shows a design pattern portion 182 of outside surface 178, and FIG. 10H shows an image camera portion 184 of outside surface 178.

FIG. 11 is a partly exploded perspective view of a hand-held modular communication device 200 that includes an information input module 202 with a numerical keypad and a puck 204 equipped with a cellular telephone, a flash camera, and an audio speaker. FIG. 11 is shown partly exploded to illustrate, with reference also to FIGS. 12B and 12D (described below), the matability of puck 204 with information input module 202, which has a rectangular opening 209 that receives puck 204. Information input module 202 and puck 204 are each of rectangular shape.

FIGS. 12A, 12B, 12C, and 12D show multiple views of puck 204 having a thin, rectangular body with generally planar opposite major surfaces. Puck 204 has near its top side margin 206 a cellular telephone antenna 208 and a Bluetooth short range radio link antenna 210. Puck 204 has on its front surface 212 a touchscreen display surface 216 that is implemented with capacitive touch sensing technology, such as TouchPad™ capacitive technology of Synaptics Inc., Santa Clara, Calif. For aesthetic and functional reasons, display surface 216 preferably occupies as much as possible of the area of front surface 212 of puck 204. Electronic circuitry, including signal control and processing circuitry and operational memory circuitry, contained within puck 204 enables cellular telephone operation in association with antenna 208 and an audio speaker 220 exposed in an opening in a back surface 222, near top side margin 206 of puck 204. A microphone 224 is placed at a bottom side margin 226 of puck 204. Display surface 216 and audio speaker 220 located on opposite surfaces 212 and 222, respectively, of puck 204 promote the cleanliness of display surface 216. Such placement of display surface 216 and audio speaker 220, as compared with a side-by-side arrangement of them along either front surface 212 or back surface 222, affords a reduction in overall length or width of puck 204. Reducing the length or width of puck 204 makes it more compact and thereby facilitates coverage by display surface 216 of as much as possible the area of front surface 212 of puck 204. The electronic circuitry of puck 204 provides operational function actuation areas on touchscreen display surface 216. The electronic circuitry is also capable of providing a keypad image on touchscreen display surface 216 to enable separate cellular telephone use from information input module 202, if desired. Puck 204 holds a SIM memory card 228 for storing telephone numbers and personal settings and a vibrating alarm 230 functioning as a silent telephone ringing device. SIM memory card 228 is positioned behind a battery 232 and is user-accessible from outside of puck 204 through a slot 229 in bottom side margin 226, and vibrating alarm 230 is positioned near top side margin 206. The presence of Bluetooth radio link antenna 210 enables use of a remote, user-worn microphone.

To accommodate placement in information input modules configured with different communication signal device locations, puck 204 is equipped with two sets of redundant, simultaneously operating infrared (IR) communication emitters and detectors, one of which sets associated with an IR link window 234 located in bottom side margin 226 of puck 204 and the other of which sets associated with an IR link window 236 in back surface 222 of puck 204. The redundant IR links ensure compatible communication links between puck 204 and different information input modules, because the shape and style of each of them can necessitate placement of the communication link window of an information input module in one of multiple established locations. In the case of information input module 202 of FIG. 11, IR link window 234 of puck 204 is spatially aligned with its corresponding IR link window in a bottom side wall 237 of opening 209 in information input module 202. In the case of an information input module that is configured to mate with puck 204 but leave open its bottom side margin 226, IR link window 236 on back surface 222 provides the communication link. Examples of a puck module in which a back surface IR link window would be spatially aligned with an IR link window on a flat surface region of an information input module include a jewelry piece and a wallet of the types shown in FIGS. 5A and 10A, respectively.

FIGS. 12B and 12D show shallow grooves 238 extending along the lengths of and located generally centrally in top side margin 206 and bottom side margin 226 of puck 204. Each of the grooves 238 supports on its bottom surface a linear electrical conductor. The electrical conductors supported in the two grooves 238 of each puck 204 preferably function as positive and negative electrodes for delivery of electrical power to puck 204. Electrical power is delivered to puck 204 by electrically conductive rods 240 (only one shown) fitted along opposite side walls 237 and 242 of opening 209 in information input module 202. Rods 240 are positioned on side walls 237 and 242 of opening 209 to provide a positive, releasable snap fit into their corresponding grooves 238 of puck 204 when it is mated with information input module 202. In this configuration, information input module 202 functions as a battery charger or a conduit for charging current for battery 232 in puck 204. Rods 240 may also be adapted to function as an alternative data and control communication link between puck 204 and information input module 202.

FIG. 12C shows a camera 246 and its associated flash assembly 248 housed in locations for operation through corresponding openings in back surface 222 of puck 204.

A recessed on-off button 250 in puck 204 makes it compatible with the matable connection in opening 209 of information input module 202. Information input module 202 has a floor 252 with an opening 254 for one or both of passage of sound emissions from audio speaker 220 and image acquisition by camera 246 and its associated flash assembly 248. Skilled persons will appreciate that pod 204 can perform certain functions separately from information input module 202. For example, if puck 204 is programmed such that touchscreen display surface 216 presents an operational dial touchpad, certain mobile telephone functions can be performed by puck 204 apart from information input device 202. There are many possible operational functions and design configurations, as indicated by the exemplary embodiments described.

Bluetooth radio link antenna 210 also enables implementation of a loss prevention feature in puck 204. The electronic circuitry of puck 204 transmits a continuous signal that is received by a Bluetooth radio link enabled key-fob 260 attached to a user's keychain, purse, pocket, or other personal item. FIG. 13 is a simplified block diagram of key-fob 260, which is a battery-operated device equipped with one or more light emitting diodes (LEDs) 262, functioning as a visual indicator, and an audible alarm. Electrical circuitry 264 allows a user to turn on or off electrical power to key-fob 260, adjust a distance control 266 to select the strength of the Bluetooth signal to correspond to a set threshold distance from puck 204, and adjust a volume control 268 to select the audible tone volume. Whenever the distance between key-fob 260 and puck 204 (either alone or mated with information input module 202) exceeds the user-set threshold distance, key-fob 260 generates one or both of an audible tone with the alarm or a visual signal with LEDs 262.

FIG. 14 is a partly exploded perspective view of a hand-held modular communication device 270 that includes an information input module 272 with an alphanumeric keypad and puck 204 programmed to operate as a PDA. Information input module 272 has its opening 209 sized to receive puck 204 by a snap fit into grooves 238 and deliver electrical power to puck 204 by electrically conductive rods 240. To accommodate placement in information input modules of different sizes and shapes, the electronic circuitry of puck 204 is implemented with image display control including image rotation to provide portrait or landscape image presentation. Such image rotation enables puck 204 to display information with its longer dimension in the vertical direction (e.g., FIG. 11) and with its longer dimension in the horizontal direction (e.g., FIG. 14), as dictated by nominal usage of the information input module with which puck 204 is mated. A signal delivered from the IR link window in bottom side wall 237 of information input module 272 to IR link window 234 of puck 204 provides an image rotation command that sets the image orientation.

FIG. 15 is a partly exploded perspective view of a hand-held modular communication device 280 that functions as a multi-purpose audio player. Audio player 280 includes an information input module 282 that is adapted to receive a puck 284 of the same size and shape as that of puck 204 with a touchscreen display surface 286 and configured to operate as a mobile telephone or a music player. Information input module 282 has its opening 209 sized to receive puck 284 by a snap fit into grooves 238 and deliver electrical power to puck 284 by electrically conductive rods 240. Puck 284 includes electronic circuitry producing audio signals that are transmitted through a suitable communication link to information input module 282, which houses audio speakers 288. A user touches touchscreen display surface 286 for music selection and actuation of other user-performed operational controls. Information input module 282 includes certain user-controlled command inputs, such as, for example, an electrical power switch 290, a volume control 292, and a digital touchpad 294 to enable operation of communication device 280 as a speaker phone.

Ultra-thin keypad 322 can be made of transparent, translucent, or opaque material to customize its appearance. Although it is about one-half the thickness of puck 204, ultra-thin keypad 322 has its opening 209 sized to receive puck 204 by a snap fit into grooves 238 and deliver electrical power to puck 204 by electrically conductive rods 240. There is no floor closing the bottom portion of opening 209. Keypad 322 holds puck 204 such that its front surface 212 and back surface 222 extend beyond the major surfaces of keypad 322 to provide user access to the functions on both the front and back of puck 204.

Embodiments of the information delivery module could be equipped with voice recognition capability to respond to voice commands, enable hands-free communication, or both. Embodiments of the information input module may contain additional power supply and processing circuitry to enable the modular communication device to perform or function in a desired manner. Moreover, providing additional simulation circuitry in the information input module could enable it to perform multiple task modes (e.g., game mode and text messaging mode).

The visual appearances of the various, indefinite number of possible embodiments of the modular multi-function device or POD humanize the interaction between technology and the user. By recognizing that mobile telephones and other portable communication devices are increasingly influenced by fashion trends, applicant created POD modules in a range of shape, color, material, and finish choices that allow users to express their individual styles and fit into users' everyday environments. POD adapts to a user's lifestyle rather than requiring the user to adapt to the limitations or unappealing look of technology. The modular design approach creates a recognizable look and a trademark, while accommodating the user's desire for customization.

In a world in which face-to-face human interactions are being increasingly replaced by technology, a modular multi-function communication device that enables an inviting, compelling, and personal experience can make a profound difference in the user's everyday life. POD achieves exactly that profound difference. Unlike mobile telephones that confine the customer to one look, limited configurations, and finite functionality, the customizability of POD allows optimum personalization, configuration, and functionality for different users and use scenarios. A user can take his or her POD anywhere—from gym, to fancy dress party, to home, to office—and have it fit into each environment with ease. By combining in one device all the user's technological needs, including telephone, PDA, camera, music files, clock, and games, POD simplifies the vast realm of technology options used in everyday life with one consistent interface. At the same time, POD becomes wearable technology that enables a user to make a unique fashion statement and express personal style.

The POD design solution is more versatile and much less expensive than any other currently available customization solution, resulting in an affordable, multi-function mobile telephone or other communication device that precisely fits the individual user's needs, desires, and aesthetic sensibilities.
